  1. Uninstall / Reinstall has been the recommended 1st step method for this issue.
  2. Did Malwarebytes find anything at all the first time you ran it? What browser are you using? If you have not done so already, read and follow all the applicable steps outlined in this pinned article at the top of the forum:
  3. It doesn’t actually run in the background, at least it should not. If you are seeing evidence of that, let us know. It just sits in your browser's plugins folder and automatically runs when you allow a web page to use it. You might want to change your setting to “ask” until you find a site that you need to always allow it. HTML5 is just a standard. No developer makes it. It's built into all browsers, so nothing to download, if a website is coded to use it, then it will just happen. Problem has been web site owners have been slow to update their sites to provide it, either totally or as a choice.
  4. If you must use still use Flash Player for some reason, then use System Preferences->Flash Player for each and every update. I allow auto updates, but at a minimum you should have it check and notify you of an update. If it fails for any reason, go only to https://get.adobe.com/flashplayer to download the installer. Lots of users have given up on Flash Player and Adobe has announce it will abandon it. Recent versions of macOS now offer to delete installers as soon as they complete there work, so that's certainly a clue as to whether to keep or not. Unless you have tight limits on how much you can download, you can always grab the latest version if you later have problems and need to reinstall. Needing to revert to a previous version is rare these days, so there is little need to hang on to anything older than the last version that worked for you. And if you are running tight on free space on your drive, old installers in your Download folder should be first to go.
  5. I can confirm that it does. @treed & I participated in discussions with the author that led up to the publication of that article. But since then it's been observed to be used to distribute additional variants and types of malware, so it's reasonable to expect additional protection updates to guard against these, going forward. It could also show up on additional web sites. The ones discovered so far have been sketchy and probably not places a savvy user would ever visit. But highly respected sites have been known to have been hacked in the past, so there's always that possibility.
  6. Yes, I saw it along with about a dozen users posting to twitter today (many retweeted by Patrick). It simply replaced the prior file (identical), so not sure why we all got the alert this time. There was also a LaunchAgent installed at the same time which nobody seemed reported, making it even more curious.
  7. Although the article is partially applicable to the Mac version of Malwarebytes in terms of it's principles, it does focused on the original Malwarebytes for Windows which is somewhat more mature in it's development. I feel confident that many of these same features will be included over time. To focus specifically on speed, this article explains Why Malwarebytes scans so fast on Mac devices.
  8. When you click on the menubar icon, does a menu pop down? If so select "Open Malwarebytes" at the bottom. Alternatively, got to your Applications folder and double click on the Malwarebytes app to launch it.
  9. Are you using a Windows PC? This is a forum for Macintosh users.
  10. Just because they are signed with a valid Apple Developer ID doesn't mean they aren't what they have been identified as. There are lots of things in the App Store and Safari Extensions Gallery that produce adware or meet the PUP definition. I recognize several of the above as just exactly what Malwarebytes says they are and are not False Positives.
  11. I can confirm that Malwarebytes for Mac and it's predecessor never ran on Mac OS 10.6.8, so yes, it's not available. I've been following similar questions from Snow Leopard users for two or three years now and never saw any answer involving free anti-virus or anti-malware (AV & AM are actually the same thing, though the former is technically mis-named). In fact, the only AV / AM software that I'm aware of that's available today for 10.6.8 is ClamXAV 2.19.2 which is only free during a thirty day trial and will stop working if a subscription is not purchased.
  12. Amazon tablets run FireOS not iOS, so you are posting in the wrong forum. Not sure whether Malwarebytes for Android is compatible or not.
  13. Yes, all malware running or installed, known by Malwarebytes to currently exist along with any PUPs that you may have installed.
  14. It is not possible to scan any external drives with Malwarebytes for Mac. It may be under consideration for a future release, but would require significant programming effort to provide such capability.
